The measures, affecting the A4076 and A40 between Haverfordwest and Milford Haven, Pembrokeshire, were brought in from Thursday, August 6. The Welsh Government order sees speed limits reduced to either 40mph or 10mph on certain stretches of the A4076. The A4076 restrictions runs from the junction with Salutation Square Roundabout to a point 43 metres east of the junction with Merlins Bridge Roundabout in Haverfordwest. A temporary 10mph speed limit and no overtaking has also been brought in on several stretches of the A4076 and A40. As well as these, the A40 is also subject to these restrictions from the Salutation Square Roundabout to the junction with Scotchwell Roundabout in Haverfordwest.
